Components Of A PC

The brain of a computer is called the CPU, which stands for Central Processing Unit. The CPU is responsible for executing instructions and performing calculations in a computer. It is considered the most important component of a computer as it controls and coordinates all the other hardware and software components. The CPU receives input from various sources, processes it, and produces output accordingly. It is often referred to as the brain of the computer because, like the human brain, it controls and manages all the operations of the computer system.

The correct answer is Central Processing Unit. The CPU is the primary component of a computer that performs most of the processing inside the system. It is responsible for executing instructions and performing calculations, making it the "brain" of the computer. The other options, such as Central Printer Unit and Centre Print Union, do not accurately represent the acronym CPU and its function.

A sound card is also known as an audio card because it is responsible for processing and producing audio signals in a computer system. It is a hardware component that allows for the input and output of audio data, enabling sound to be played through speakers or headphones and allowing for the recording of audio through a microphone. The term "audio card" is commonly used to refer to this specific component of a computer system.

RAM stands for Random Access Memory. This is a type of computer memory that allows data to be read from and written to quickly. Unlike other types of memory, such as Read Access Memory or Read Act Memory, RAM allows for random access, meaning that any piece of data can be accessed directly without having to read through the entire memory. Random Access Memory is essential for the efficient functioning of a computer as it provides temporary storage for data and instructions that are actively being used by the CPU.

The two output devices in a PC are the monitor and printer. The monitor displays visual information such as images, videos, and text, allowing the user to see what is happening on the computer. The printer, on the other hand, produces hard copies of digital documents or images, allowing the user to obtain physical copies of their work. Both devices play a crucial role in providing visual output and enabling users to interact with and share information from their computer.

A motherboard is a main circuit board in a computer that holds many of the crucial components of the system, such as the CPU, memory, and connectors for attaching additional boards. It serves as a hub that allows these components to communicate with each other and enables the computer to function properly.

The speed of a CPU is measured in Megahertz and Gigahertz. Megahertz (MHz) and Gigahertz (GHz) are units used to measure the clock speed of a CPU, which indicates how many cycles the CPU can complete in a second. A higher clock speed generally indicates a faster CPU, as it can execute instructions more quickly. Therefore, Megahertz and Gigahertz are the correct units for measuring the speed of a CPU.

The Central Processing Unit (CPU) is often referred to as the brain of the computer. It is responsible for executing instructions from software programs by performing calculations and managing the flow of data between different hardware components. The CPU plays a crucial role in determining the overall performance and speed of a computer system. While all the options listed are important components of a PC, the CPU specifically handles processing tasks and is essential for the functioning of the system.

The hard drive is a crucial component of a PC responsible for storing data permanently, including the operating system, software applications, and user files.
